WATER-CQOLED FURNACE-VALVE AND CHAMBER THEREFOR.

Be it" known that I, WILLIAM R. PALMER, a citizen of the United States,residing at Bridgeport, county of. Fairfield, State of Connecticut, haveinvented a new and useful VVater-Cooled Furnace-Valve and ChamberTherefor, of which the following is a specification.

This invention relates more especially to valves for reversing furnacesand has for its object to provide a valve of this type which shall besimple and inex ensive to construct, easy to repair,'in whic all partsshall be perfectly water-cooled, and which shall be so constructed thatneither the incoming gas nor the outgoing products of combustion cancome in contact with water.

With these and other objects in view I have devised the simple and novelreversible water-cooled valve, of which the following description inconnection with the accompanying drawings is a specification, referencecharacters being. used to indicate the several parts.

Figure 1-is a plan view of so much of the fines of a furnace as isnecessary to illustrate the two being used in each furnace; Fig. 2' aplan view on an enlarged scale, illustrating the ei ation of a valve,the ositioncorrespon ing with the osition o the valve toward the bottomof the sheet in Fig. 1; and Fig. 3 is a vertical section on the line 3-3in Fig. 2, looking in the direction of the arrows.

10, 11, 12 and 13 denote flues leading to and from the valve to thecheckers, so called, which are not shown as they form no portion of thepresent invention.

14 and 15 indicate fines (shown in dotted lines only) leading downwardfrom the valves to outgoing flue 16 (shown only in dotted lines) whichleads to the stack indicated by 17. i

18 indicates the incoming gas flue and 19 the incoming air flue, whichis shown as provided with a sliding damper 20. It is not considerednecessary for v the urposes of this specification to illustrate tli tionand arrangement of the flues in detail, as all reversing furnaces mustbe provided with these'flu-es and their construction and arrangement ismerelya matter of detail.

21 denotes a valve as a whole,-each valve being. adapted to oscillate ina chamber 22 formed in thebrickwork.

23 denotes an open reservoir which may Specification of Letters Patent.Application filed June 29, 1908. Serial No. 440,839.

be a casting and which rests upon the brick of the valve chamwork andforms the top her. On one side of t e reservoir (the left as shown inFigs. 2 and 3) is a cross-wall 24,

of a pipe 28.

29 denotes vertical pipes, one at each corner of the chamber andprojecting partially into it, which lead from reservoir 27 up throu hthe bottom of reservoir 23 and are provided with nipples or nozzleswhich discharge into reservoir 23, the overflow of the latter reservoirrunningl over the top of and passing out of Water under any requiredpressure throu h the reservoirs and pipes insures that t evalve chambermay be kept at as low a temperature as may be required.

Since the water is first supplied to the passes upward through the pipes29 and dischar es' into the upper reservoir which, in the curl? would betaken by such steam as might be generated and its flow would not be"obstructed by such steam, and. there is no liability of an explosiondueto such generation of steam.

If preferred, pipe 28 may be dispensed with and the water supply ipe maybe connected to one of the vertica -pi es 29- and forced through said pie 29 into t is lower reservoir, water passing rom the lower to the upperreservoir through the other three pipes 29.

The valve is itself a reservoir and consists simply of an angular frame31 and side plates 33 riveted thereto as at 34..

The upper bar of the frame is provided with a hollow {partial 35 whichis adapted to oscillate in a reservoir 23.

37 denotes a collar r i up er endof the journa hu and collar 37 Ipreferably place collars rovided with circular races to receive ballsorming a ballbearing, which su ports the valve and permits 1t tooscillate reely, the valve beingoperated by idly secured to the means ofa hand lever 39 secured to collar 37 I Water is supplied to the valve bymeans ot a odiment shown, isopen, the water flows inthe direction thatub 36 which extends upward from the bottom of termediate the indicatedby ,38,

pipe 40 which extends downward nearly to the bottom of the reservoir inthe valve, which is indicated by 41. Pipe 40 is rigidly securedconcentrically in a discharge pipe 42, which is of larger diameter thanpi e 40, leaving ample space outside of pipe 40 or the Pipe 42 isrigidly secured-in place and the journal of the reservoi'r'oscillatesexteriorly thereto. It will be readily understood from Fig. 3 that hub36 is formed integral with or is secured to the bottom of reservoir 23,and that the 'ournal of the reservoir oscillates within the ub and fixedpipe 42 passes through the journal. At the upper end of pipe 42 is a hub43 to which pipe 40 is rigid y secured and which is provided with anozzle 44 for the discharge of water from pipe 42 into reservoir 23.Water to cool the valve enters through pipe 40 which carries it nearlyto the bottom of reservoir 41. The outgoing water passes throughdischarge pipe 42, lying outside the pipe 40, and is discharged intoreservoir 23. It will thus be seen that the water from reservoir 27below the valve and reser voir 41 within the valve flowsinto reservoir23, passes over cross-wall 24 into the trough and out through dischargepipe 26.

The entire weight of the valve may be supported by the ball hearing. Inorder to retain the valve in a central position and prevent displacementI provide a central lug 47 on the under side of the valve frame whichengages a step in a central hub 46 in reservoir 27, as clearly shown inFig. 3. 7

45 denotes stop ribs in the valve chamber formed upon the upper wall ofreservoir 27 and the under wall of reservoir 23, which are placed insuch alinement relatively to pipes 29 that they receive the blow of thevalve in swinging it to position and prevent the blow being upon thepipe, the ribs acting to stop the valve at just the instant that itcomesinto engagement with the pipes, the pipes and the ends of the valvemakin seals so asv to prevent escape of air, gas or t e products ofcombustion as may be.

49 denotes the usual stack damper and 50- check dampers in fines 14 and15. The action of these dampers, however, is wholly unimportant so faras the principle of the present invention is concerned.

The operation is as follows: It is of course well understood that inreversible furnaces air and gas are admitted separately and pass throughheating chambers, commonl called checkers, and that after being heatethe air and gas are mixed and pass to the combus tion chamber, theproducts of combustion passing out through similar chambers or checkers.While this is taking lace, the

heated by the outgoing products of combustion, and the checkers upon theother side are losing their heat, which is being utilized'in heating theincoming air and gas. After the furnace has been running for apredetermined time, for examplefifteen minutes, the passage of the airand gas and the products of combustion is reversed and the air and gasare passed through the previously heated checkers and the checkerspreviously used for heating purposes are re-heated by the outgoingproducts of combustion, the object being to heat the incoming air andgas to the highest degree possible by passing them through checkerspreviously heated by the outgoing products of combustion, the reversingof the air andgas and the products of combustion being affected by thevalves which are subjected to intense heat as they are constantlyexposed to the highly heated outgoing products of combustion within ahighly heated chamber. My present invention enables me to cool both thechambers and the valves by means of running water and to maintain themat a low enough temperature to prevent injury to the valves. Turning nowto Fig. 1, air enters the valve toward the bottom of the sheet and isturned by the valve proper into flue 13 and passes through checkers (notshown) to the mixing and combustion chambers (not shown). Gas entersthrough flue.1 8 and is turned by the valve proper toward the top of thesheet into'fiue 12 and through checkers (not shown) to the mixing andcombustion chambers (not shown). The outgoing products of combustionreturn to the valves by means of fines 10 and 11 and are turned bythevalves into vertical flues 14 and 15, which communicate with outgoingflue 16 leading to the stack. After a predetermined time the valves willbe reversed, the lower valve will be turned to the position in which theup per valve is shown in Fig. 1, and the upper valve will be turned tothe position in which the lower valve is shown. Everything will now bechanged. The incoming air will pass to highly heated checkers (notshown) through flue 11, the incoming gas will pass to highly heatedcheckers (not shown) through flue 10, and the outgoing products ofcombustion will come through flues 12 and 13 and will be turned by thevalves into flues 14 and 15 leadingto outgoing flue 16 and the stack asbefore.

The valve proper may be easily removed for repairs or be replaced byremoving nipples or nozzles 30 and the upper reservoir and lifting itout of the chamber.
